Thymidylate kinase (EC 2.7.4.9; dTMP kinase) catalyzes the phosphorylation of thymidine 5′-monophosphate (dTMP) to form thymidine 5′-diphosphate (dTDP) in the presence of ATP and magnesium: ATP + thymidine 5′-phosphate ADP + thymidine 5′-diphosphateThymidylate kinase is a ubiquitous enzyme of about 25 Kd and is important in the dTTP synthesis pathway for DNA synthesis.
